The paper introduces an
optimized multicore CPU implementation of the genetic algorithm and compares
its performance with a fine-tuned GPU version. The main goal is to show the true
performance relation between modern CPUs and GPUs and eradicate some of myths surrounding
GPU performance. It is essential for the evolutionary community to provide the
same conditions and designer effort to both implementations when benchmarking
CPUs and GPUs. Here we show the performance comparison supported by
architecture characteristics narrowing the performance gain of GPUs.
